A ALVE FORGAS-ENGINES.

Application filed we so, 1913. Serial in. 776,477.

To allwhom it may concern:

Be it known that-I, RICHARD'E. MEYER, a citizen of the United States vof America,

residing at Detroit, inthe county of; Wayne and State of,Mi-chigan-; have invented certain new and useful j. Improvements in Valves for Gas-Engines, of which the following is a specification, reference. being had therein to the-accompanying 'd'rawings.

This .invention relates to valves for internal combustion or explosive engines, and to an arrangement thereof whereby the use of extra packing strips is avoided and whereby the valves inthemselves are thoroughly cooled, n v

-'Ih e invention consists in the matters hereinafter set forth and more particularly pointedout in the ap'piendedclaims.

In the drawings, Figure 1 is a view' in vertical sectionof a; motor provided with valve gear that embodiesfeatures of the invention; Fig. 2 1s a viewvin transverse sec tion through. the cylinders; Fig. 3 is a viewin detail of a preferred form of valve closure; Fig. 1 is a viewin detail. of the closure and piston packing rings; and F igJ 5 is a view in section in detail, showing the attachment of the closure to a driving gear.

Referring to the drawings, an englne bait; 1 and crank case 2 of any suitable type, sup

port cylinders 3 that are preferably disposed in pairs, although any arrangement that is desired may be used. Thewalls of the cylinders are provided with a water space 4 whereby they are efficiently cooled or .water jacketed. An annular gear ,5 is

'rotatably secured, as an overlying collar 6,-

:the' sleeves expand .against', the cylinder walls, packmgrings 14 are necessaryto insure fit between the piston and the sleeve.

at least always overlaps a transverse portion-of the line of division 10 of the closure. Asuitable valve gear train, indicated at 15, or other. like connection is used for rotating one of the closures 6. -The closure of adjacent cylinders are'interconnected to' obtain the necessary synchronous movement of the valves Lubrication is provided for by means of one or more spirally, disposed channels 18 extending from the. abutting; margins of the closure to the upper end, so .that lubricantis carried upwardly and dis- I tributed over the closure.

As the Walls of the cylinders are water therewith along the surfaces which need the most lubrication and as they expand readily throughout their length against the cylinder walls a sufficiently tight fit is insured to '(so The rings are disposed so that one of them prevent appreciable leakage. The construction issimple, the valves are noiseless and Obviously, changes in the details of construction may be made without departing their operation when once'regulated is al- ',ways in correct time with the engine cycle.

What I claim is 4 der, an expansible split valve sleeve con not care to limit myself to any particular 9e '4 1.

The combinationfgwith an explosive engine and a ported cylinder thereof, of a valve sleeve rotatable in the cylinder split longitudinally to yieldingly expand against the cylinder walls, a piston reciprocable in the sleeve, and means rigidly connected to said sleeve intermediate-the split edges thereof and loosely connected-to said sleeve at the split edges thereof for turning the sleeve in timed'relation to the piston movement to control ;the cylinder ports.- I

3. The combination in an explosive en gine, of a ported cylinder, a gear, rotatably mounted thereon, a yieldingly expansible valve sleeve connected to the gear to turn therewith and journaled in the cylinder to which it conforms, said valve sleeve having a split inter-locked portion and a lubricatinggroove extending from the upper end of said sleeve to a point intermediate the ends thereof and means for rotating the gear Whereby'the sleeve controls the cylinder ports.

4E. The combination With an explosive en gine'having a ported cylinder, of a valve sleeve split longitudinally with the resultant abutting margins in interlocked engagement, means rigidly connected to said sleeve intermediate the split edges thereof and loosely connected to said sleeve at the split edges thereof to support the sleeve for rotation in the cylinder, and a piston for the cylinder reeiprocable in the sleeve.

5. In an explosive engine, a ported cylinder, an expansible-split valve sleeve having one or more ports and conformable to and rotatable in the cylinder for controlling the por ts thereof, a piston for the cylinder reciprocable in the rigidly connected to said sleeve intermediate the edges thereof and loosely connected to said sleeve and the split edges thereof for rotating the sleeve in timed relation to the engine cycle.

in the cylinder reciprocable in the sleeve,

means rigidly connected to said sleeve intermediate the split edges thereof and loosely connected to said sleeve at the split edges thereof for rotating the sleeve in timed relation to, the engine cycle, the'sleeves being longitudinally split With the resultant margins rectangularly notched and in tel-locked, and packing-rings on the piston so disposed that oneat least of them always overlaps a transverse portion of the interlocked seam.

In testimony whereof I afiix my signa-* ture in presence of .tWo Witnesses.
